Rainbow Trout Study Concludes

Posted on: December 14th, 2018 by Leslie_Zucker

Researchers from the U.S. Geo­log­i­cal Sur­vey (USGS), NYS Depart­ment of Envi­ron­men­tal Con­ser­va­tion, and the firm Eco­Logic con­cluded a study look­ing for one poten­tial cause of recent Rain­bow Trout pop­u­la­tion declines in the Ashokan Watershed.

The study was launched when the num­ber of Rain­bow Trout in the upper Eso­pus Creek, a major trib­u­tary drain­ing into the Ashokan Reser­voir, showed a pre­cip­i­tous drop between 2009 and 2013.

One poten­tial cause for the decline was the estab­lish­ment of two inva­sive fish in the reser­voir — the Alewife estab­lished in the 1970s and White Perch in the 2000s. Both species are not native to the Ashokan Reser­voir water­shed and have the poten­tial to change the type and abun­dance of food avail­able to other fish, includ­ing Rain­bow Trout.

The researchers did an analy­sis of fish caught in the Ashokan Reser­voir over the past 70 years, look­ing at the rate of Rain­bow Trout growth before and after Alewife and White Perch became established.

Sur­pris­ingly, the growth of Rain­bow Trout appeared to increase over recent decades. The largest increases in both growth and con­di­tion of Rain­bow Trout were observed after the intro­duc­tion of White Perch. This was unex­pected con­sid­er­ing White Perch should be poor prey for Rain­bow Trout and may also com­pete with Rain­bow Trout for food.

The researchers did not con­clude that White Perch in the reser­voir ben­e­fit­ted Rain­bow Trout. Instead, other changes in the water­shed and its ecol­ogy may have affected the growth and con­di­tion of Rain­bow Trout over the decades.

Future research and man­age­ment may focus on iden­ti­fy­ing, pro­tect­ing, and restor­ing areas in which Rain­bow Trout spawn.

In fur­ther good news, annual elec­trofish­ing sur­veys at six sites on the Eso­pus Creek and its trib­u­taries have shown that Rain­bow Trout spawned very suc­cess­fully over the past few years, accord­ing to George.

The AWSMP pro­vided fund­ing for this study through a Stream Man­age­ment Imple­men­ta­tion Pro­gram (SMIP) grant. A peer-reviewed arti­cle on the study was pub­lished in the Octo­ber 2018 issue of the North Amer­i­can Jour­nal of Fish­eries Man­age­ment. For more infor­ma­tion see

Floodplain Manager Trainings Start in January

Posted on: November 30th, 2018 by Leslie_Zucker
CCEUC Educator Brent Gotsch is a Certified Floodplain Manager (CFM), a certification recognized both nationally and by the Association of State Floodplain Managers. Gotsch offers a free course in the NYC Watershed on preparing to become a CFM.

Spotted Lanternfly Discovered in New York State

Posted on: September 20th, 2018 by Brent Gotsch

Recently, the New York State Depart­ment of Envi­ron­men­tal Con­ser­va­tion (NYSDEC) and the NYS Depart­ment of Agri­cul­ture and Mar­kets (NYSDAM) announced that Spot­ted Lantern­fly (Lycorma del­i­cat­ula) was dis­cov­ered in Albany and Yates coun­ties. So far only two sin­gle adult insects have been dis­cov­ered but the con­cern is that there could be more. First dis­cov­ered in Penn­syl­va­nia in 2014 Spot­ted Lantern­fly (SLF) has since been found in New Jer­sey, Delaware, Vir­ginia, and now New York.

SLF is an inva­sive species that is native to Asia, specif­i­cally parts of China, India, and Viet­nam. With no native preda­tors to keep its pop­u­la­tion in check, there is con­cern that SLF could have a sig­nif­i­cant impact on our native forests. Although their pri­mary source of food is the Tree of Heaven (Alianthus altissima), an inva­sive species itself which con­trary to pop­u­lar belief grows in more than just Brook­lyn, it has been known to feed on a wide vari­ety of plants includ­ing grapevine, hops, wal­nut and sev­eral types of fruit trees. This has the poten­tial to impact sev­eral multi-billion dol­lar indus­tries includ­ing grape and hop pro­duc­tion, the fruit grow­ers and log­ging. Sev­eral ripar­ian species are also at risk includ­ing maples, oaks, pines, poplars, sycamores, and wil­lows. This, cou­pled with the die-off of hem­locks and ash trees caused by Hem­lock Wooly Adel­gid and Emer­ald Ash Borer, respec­tively, could have severe con­se­quences for ripar­ian cor­ri­dor ecosys­tem health and stability.

SLF lay their eggs between the months of Sep­tem­ber and Decem­ber. Newly laid egg masses have a grey mud-like cov­er­ing that can take on a dry cracked appear­ance over time. Old egg masses appear as rows of 30–50 brown­ish seed-like deposits in 4–7 columns on the trunk that are roughly an inch long. Eggs hatch between the months of May and June. SLF nymphs emerge and are black with bright white spots. At this stage they are roughly the size of a pen­cil eraser. Over the next sev­eral months they grow larger but main­tain their col­ors until between the months of July and Sep­tem­ber where they turn bright red with dis­tinct patches of black and bright white spots. From July through Decem­ber SLF matures into an adult that has wings that are about 1-inch-long that are grey with black spots. When the wings are opened it reveals a red underwing.

SLF feeds by using it mouth­parts to pierce and then suck the sap from the trunks, branches, twigs and leaves. This cre­ates a weep­ing wound of sap. As it digests the sap, SLF secretes a sub­stance known as hon­ey­dew. This com­bined with the flow­ing sap tends to col­lect at the base of the trunk and pro­vides a fer­tile area for the growth of fungi and mold that may stunt plant growth or even cause pre­ma­ture death. It may also attract bees, wasps, ants and other insects to the site, fur­ther stress­ing the plant.

If you think you have SLF on your prop­erty please take a pho­to­graph of either the nymph, adult insect, egg mass, or infes­ta­tion sign along with an item for scale (such as coin or ruler) and email them to Be sure to note the loca­tion includ­ing address, inter­sect­ing road, land­marks or GPS coor­di­nates. Also report the infes­ta­tion to iMap­In­va­sives.

For more infor­ma­tion on SLF be sure to visit the NYSDEC Web­site on SLF as well as web­sites devoted to SLF on the Penn­syl­va­nia Depart­ment of Agri­cul­ture and Penn State Exten­sion websites.

AWSMP at Olive Day 2018

Posted on: September 4th, 2018 by Brent Gotsch

AWSMP will be attend­ing this year’s Olive Day on Sep­tem­ber 8 from 9:00 am to 5:00 pm at the Lester Daivs Park located at 686 Wat­son Hol­low Road in West Shokan, NY (right next door to the Olive Town Hall). Olive Day is an annual event that cel­e­brates all the things that make the Town of Olive a spe­cial place to live. There will be food, live music, a vari­ety of ven­dors, local and regional orga­ni­za­tions with edu­ca­tional dis­plays, and activ­i­ties for chil­dren and fam­i­lies includ­ing the always pop­u­lar frog race!

AWSMP will have a table with pro­gram lit­er­a­ture as well as an edu­ca­tional dis­play. We will also be bring­ing our stream table. The stream table shows how water inter­acts with and shapes the land­scape around it. It also shows how human inter­ven­tion in streams can change how water flows and the shape and depth of the stream.

Stop on by to see the stream table in action, pick up some lit­er­a­ture and say hi. We look for­ward to see­ing you at this year’s Olive Day!

AWSMP Youth Educator Matt Savatgy uses the stream table to show youth how manipulation of the stream channel can cause changes in the surrounding landscape during Olive Day 2017.

Riparian Buffer Grand Opening!

Posted on: August 27th, 2018 by Leslie_Zucker

Join the Catskill Cen­ter and the AWSMP at the Mau­rice D. Hinchey Catskill Inter­pre­tive Cen­ter (CIC) on Thurs­day, August 30 from 12pm — 1pm for the Grand Open­ing of a ripar­ian buffer! The buffer is located along a small forested stream at the back of the CIC park­ing lot. Meet for a rib­bon cut­ting at the trail bridge where the buffer is located. Streams ben­e­fit in mul­ti­ple ways from hav­ing native veg­e­ta­tion on their bor­ders. This buffer fea­tures Catskill native species and inter­preted sig­nage that iden­ti­fies the plants and explains the impor­tance of stream­side veg­e­ta­tion. The buffer was installed with the help of vol­un­teers who worked hard to clear inva­sive plants from the site. The buffer will con­tinue to be main­tained by vol­un­teers, who are gath­er­ing before the grand open­ing from 9am — 12pm for another Inva­sive Plant Pull! Bring your fam­ily and friends to learn more about how you can main­tain clean, cool Catskills water on your property.

Staff from the Ulster County Soil and Water Con­ser­va­tion Dis­trict (SWCD) will be on hand to answer your ques­tions. The native plant buffer was planned and installed by the Catskill Streams Buffer Ini­tia­tive, a pro­gram of the Ulster SWCD and NYC Depart­ment of Envi­ron­men­tal Protection.


Bankfull Flows on Friday

Posted on: August 20th, 2018 by Tim Koch

On the evening of Fri­day, August 17th, 2018 some­thing very impor­tant hap­pened in the world of stream sci­ence and man­age­ment. The Eso­pus Creek, Birch Creek, and Wood­land Creek reached “bank­full discharge”.

Bank­full dis­charge is the amount of water flow­ing in the stream when the chan­nel is com­pletely filled to the brim, mea­sured in cubic feet per sec­ond (cfs). At bank­full, all the water is still con­tained within the chan­nel. Once bank­full has been exceeded, water spills out onto the flood­plain and the stream is tech­ni­cally flood­ing. The pho­to­graph below shows the Stony Clove Creek at near bank­full flow. The  unde­vel­oped flood­plain vis­i­ble on the left is acces­si­ble to the stream and ready to accept any flood waters in excess of bankfull.

(a) Stream cross sec­tion show­ing bank­full stage, (b). the head­wa­ters of Stony Clove Creek flow­ing at ~800 cfs, approach­ing bankfull

In the humid north­east, most streams will see a bank­full flow event every 1.5 years on aver­age. The last time we saw a bank­full flow in the Ashokan water­shed was Octo­ber 2017.

If any flow over bank­full means that the stream is flood­ing, then we can expect our rivers and streams to flood at least once every year and half. This is nat­ural, sta­ble stream behav­ior and high­lights the impor­tance of flood­plain management.

Bank­full dis­charge is crit­i­cal to stream man­agers because over time it is the flow that moves the largest amount of sed­i­ment, effec­tively shap­ing and main­tain­ing the chan­nel form. Due to the impor­tance of bank­full dis­charge for chan­nel main­te­nance, some of the research projects that we fund at AWSMP have trig­gers that are acti­vated fol­low­ing bank­full flow events.

Below is a chart that com­pares the stream flows observed on Fri­day the 17th (far right) to bank­full dis­charge. The Q1.5 col­umn is an esti­mated bank­full dis­charge based on sta­tis­tics. This is a use­ful esti­mate for bank­full when field derived val­ues are not avail­able. The most accu­rate way to deter­mine bank­full dis­charge is to read the stream. A well-trained eye can locate bank­full indi­ca­tors in the field such as depo­si­tional fea­tures or changes in bank slope, veg­e­ta­tion, and par­ti­cle size. By using these indi­ca­tors as a guide to mea­sure the dimen­sions of the stream chan­nel, highly accu­rate bank­full dis­charge val­ues can be cal­cu­lated (mid­dle column).
